Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] It can be understood that when the lithium battery body 4 generates heat, the heat of the lithium battery body 4 will diffuse to the containing cavity 3 and the heat dissipation cavity 27, and the cooling plate 14 and the blowing part 28 will be started. When the blowing part 28 blows the cold air of the cooling plate 14 to the heat dissipation cavity 27, the heat dissipation cavity 27 and the containing cavity 3 will be cooled, so that the heat is discharged from the air outlet 24; the cooling plate 14 will produce condensed water in the cooling process. Since one side of the guide frame 13 is inclined toward the drain hole 25, the cooling plate 14 is inclined along one side of the guide frame 13, so that the condensed water is discharged from the drain hole 25 under the action of gravity, thereby avoiding the contact between the condensed water and the lithium battery body 4 and avoiding damage to the battery body.

[0024] In addition, when the blowing part 28 blows air to the refrigeration fins 14, part of the air flow will be discharged from the drainage holes 25, thereby accelerating the discharge of condensed water.

[0026] It is understandable that when the blowing part 28 blows the cold air from the refrigeration plate 14 to the heat dissipation cavity 27, part of the condensed water will turn into water vapor and enter the air inlet slot 15. The water-absorbing material is loaded inside the filter box 18, thereby facilitating the filtration of the water vapor and further preventing the battery from getting damp.
